ABSTRACT:
A thumb-sized tape cassette having a rectangular housing with top, bottom, front, back and side walls. The front wall is provided with a center opening and side openings disposed on opposite sides of the center opening. A tape member, which runs between supply and take-up reels within the cassette, is guided in a run behind the front wall and is accessible through the front wall openings. A pressure-pad spring is supported on a post within the housing, this spring being formed as an integral continuous-surfaced leaf spring having only two bends therein to define a central section between the two bends and a leg extending from each of the respective bends. A pressure pad is secured to each leg; and the central section is supported on the support post. A pair of fulcrum posts is provided within the housing on either side of the support post to contact a surface of the leaf spring and provide a respective fulcrum for each leg.
